Operating Instructions

2. Wet Vacuuming
When vacuuming liquids, ensure the foam filter is installed. The vacuum is equipped with a float mechanism that will automatically shut off suction when the tank is full to prevent overflow. When this occurs, turn off the vacuum, unplug it, and empty the tank.

Maintenance
1. Emptying the Tank
To empty the tank, unlatch the side clips and lift off the power head. For dry debris, you can use the disposable dust bag for easy removal. For liquids, utilize the drain port at the bottom of the tank for convenient emptying.

2. Filter Cleaning and Replacement
The washable cartridge filter can be cleaned by tapping off loose debris or rinsing with water. Allow it to air dry completely before reinstallation. The foam filter should also be rinsed and air-dried. Replace filters as needed to maintain optimal performance.
3. Hose and Cord Storage
The vacuum features integrated storage for the hose and power cord. Wrap the hose around the top handle and secure it with the side wraps. The power cord can be wrapped around the handle for neat storage.
